In the accompanying drawings, like referfor holding the labels and the ence numerals refer to like parts.

Referen'cenumeral '1 indicates the frame {of the machine, which frame consists of the end pieces 2 and 3 which are. connected toperspective view of the guides gether by the sidebars 4 and 5. These side bars are connected at suitable intervals bv the cross bars 23,28, 90, 91, 92 and 93, 95,-

96. Short brackets 94: areused for sup porting the bars 22 and 22 from the sides without interfering with the travel of the chain.

The ends 2 with the'legs'ti and 7 shown in Figs. 4 and 9. Mou-ntedon the bars 4 and 5 are bearings for various shafts as follows:

. The bearing block 8 for the shaft 9 and the bearing block 10 for the shaft 11. Similar bearing blocks are provided on theoppo site side'of the machine for both of these which is "be understood that there are. two of the and 3 each have integral there-' shafts. .The bearing block 12 is provided in supported the main power shaft 13 andthe shaft 14. 'On the main power shaft 13 is provided the pinion 15 whichmeshes chains20 as is shown-in Fig. Band the sprocket wheels 18 and 19 are provided in Eairs accordingly on theirrespective shafts.

ounted on the frameof the machine is the hopper-21 in which are contained the cigaretteboxes'orother packages on which the revenue stamps or label's'a-re to be affixed.

The chain 20 travels across the bottom of ice this hopper and operates to take the cigarette pac ages one at a time as follows:

Between the hopper and the chain is provided the guides 22 and 22 upon which the bottom package in the hopper rests. The chain 20 is adapted to travel under the on space between the guides 22 and 22. ee Fig. 9). To the right of thehopper are also provided the guides 23 and 23 and the cigarette boxes, as they travel from the hopper to the right, in Fig. 4, pass between the lower guides 22 and 22 and the upper guides Fig. 8. As is shown in Fig. 8,they have the upright member 27 or head and the horizontal member or tail 27 The horizontal member 27 is intended to slide along and make contact with the bar 24, (see Figs. '1, 4 and 9), holding the member-27 firmly in an upright position as it travels under the hopper so that it can properly push the bot-. tom package along between the guides 22,-

22", 23 and 23 from the hopper to the labeling mechanism. The pushers 27 are held in the position shown in Fig. 8 when traveling forward by the bar 24 which keeps them from falling back and by the shoulders 27 which make contact -withthe lugs 26 which prevent them from falling forward. The bar 24 ends so as to leave the pusher 27-free to swing back when the box has been pushed just beyond the rollers 80 and 81.

Each of the sprocket wheels 18 and 19 is provided with seven teeth and the chain 20 is provided with links. that are any suitable multiple of this number, -preferably as is shown in the drawings of twenty-eight links, the chain also bein four pusher'plates, the ratio of the gearing being such that the chain will feed one box for each revolution of the shaft 11 and for each revolution of the shaft 13. The pusher plates .are spaced apart on the chain con-.

siderably more than the length of the box for the purpose of bringing the boxes intermittently'to the labeling mechanism. That is, with an interval between the boxes as 1 they are fed to the labeling mechanism.

Mounted on the frame of the machine is the hopper 30 in which is contained the labels 3]. or the revenue stamps that are to be afiixed to the packages. lin the sides of this hopper are formed the grooves 32. In the hopper, the traveler 33 is adapted to move. This traveler has a pin 34 extending through it which engages with the grooves 32 in the-sides of the hopper. hastened to is provided one end of which provided with a wearer the pin 34 are the strings 35 which pass around the idle pulley 36 at the front of the hopper and around the winding drums 37 at the rear of the hopper which drums are integrally connected by a sleeve, which sleeve is in turn mounted on the shaft 38 on which it is adapted to turn. The spring 39 I is connected to the shaft 38 and the other end of which is connected to the pin 40. For the purpose of connecting the shaft 38 to the drums 37 so that the'drums can be rotated by the spring 39, I provide the ratchet wheel 41 which is keyed to the shaft and the pawl 42 which is pivotally mounted on one of the drums 37. By this arrangement it is possible to turn the shaft 38 winding up the spring 39 to any desired tension without moving the drums 37 thus regulatingthe tension on the cords 35 by which the traveler 33 is driven. At the open or forward end of the hopper are formed the flanges 130 and 131, which flanges are bent .up on the sides of the magazine between which flanges is a slot in which-works thepad 72 on the feed roller 71. These flanges extend only part way up on the reservoir, they being left short so that the end of the label contained in the reservoir will be exposed above them.

At the open end of the magazine 30 a selecting mechanism is provided for the purpose of transferring the labels or revenue stamps, one at a time from the magazine and applying them to the boxes and this selecting mechanism will now be described as follows:

Mounted on the frame of the machine is the stud 45 on which is mounted the idle gear 46. Mounted on the frame of the machine is the bearing block 47 in which is,

mounted the shaft 48 having the pinion 49 thereon. Also mounted in the bearing block is the shaft 50 having'the pinion 51 thereon. The shaft 50 extends through the machine and has the pinion 52 thereon, (see On the shaft 57 is provided the sucker 61 which is hollow as shown at 62 and has openmgs 63 n the face thereof as is shown in Figs. 5, 6 and 7 A crank is formed'at each end of the sucker integral therewith. The crank at one end is used to support the sucker on the shaft 57 and the crank at the other end is hollow as shown in Fig. 5 and means i the tube 64 is attached thereto which tube magazine to the package. The label is also I segmental surfaceby the paste roller 76 to .which paste is fed by the roller 77 which runs in a reservoir of suction pump 66 which suction pump has a piston 67 therein which is driven in one direction by the eccentric 68 on the shaft 13 and is driven in the other direction by the compression spring 69. The parts are so timed that the pump will cause a suction in the sucker 61 when the sucker 61 is rotated to the position shown in Fig. 7 which suction is maintained as the sucker rocks toward the position shown in ;Fig. 6. I

When the sucker is in theposition shown in Fig. 7, the suction will cause the first label to adhere thereto and will bend it to the position shown in Fig. 6, the remaining labels retaining their normal position.

Coiiperating with this sucker is the retaining device 70 carried on the shaft, 60 which rocks to press against the labels in the magazine 30 and grip them after the suction device has pulled away the first label and holdsthem until the feed roller 71 has pulled down thedabel selected by the sucker. 25

he selected label is fed down and pasted as follows:

' Mounted on the shaft 54 is the feed roller 71 having the rubber pad 72 thereon. This rubber pad is adapted to make contact with and draw down the outer label, thatlisthe one that has been bent out at the top by the suction device. This rubber pad 72 is about three-fourths of the length of the label to be fed, thereby. As the roller 71 and its pad 72 rotates, the edge of the pad 7 2 makes contact with the label substantially on the line horizontal with the shaft 54, on

which the roller is mounted and draws the label down, feeding the label to the paste roll 73 mounted on the shaft 48. Opposite the paste roll is provided the feeding roller ,7 4 between which and the paste roll .7 3, the

label is carried down. Both the paste roll 73 and the feed roller 74 have annular grooves centrally thereof as is. shown in Figs. 10 and 13. Extending through these annular grooves to the feed roll 71 is provided the vertical stationary guides 75 (see Figs. 4, 13 and 14), between which the label is guided as it moves downwardly from the held against edgewise movement by the guides 75 and 75. (See Fig. 14). The paste roll 73- has a raised segmental surface that is slightly shorter than the length of the label.' Paste is-applied to this raised.

ripheral velocity of the roller 73 is greater.

than the peripheral velocity of the roller 76 and the roller 76 in turn has a reater peripheral velocity than the roller 7 and the earing is arranged to secure this result. his-is for the purpose of securing better ers and 81 (see Fig. 4),

paste 78. The peuntil it strikes the pocket 79 by which it is held in position so that it standsacross the path of movement of the package. As-the package is carried forward by the chain 20 heretofore described, the end of the package engages with the middle of the label and carries the label forward with it. The rollare provided between which the package must pass, which rollers serve to double the label over the package and press it down on the package.

The pushers 27 carry the packages forward beyond the guides 75 and pocket 79, (see Fig. 4), so as to leave the space open for the next label as it is fed down. The next package as it is fed along, picks up this label and carries it forward, pushing the preceding package ahead of it and in this manner, the packages are fed successively through the machine and the labels are affixed thereto. The upper bar 22 as shown in Fig. 1, extends continuously from one end of the machine to the other while the lower bar 22, extends as is shown in Fig. 4, being interrupted by the roller 80 and terminating short of the end of the machine to permit the packages to drop through into the delivery chute 86.

The bar 23 extends from the cross bar 23 to the cross bar 23 and the bar 23 extends from the cross bar 23to the roller 81. In line with the bar 23 is provided the flat spring 82 which spring is fastened at one end to the bearing block that carries the roller 81 which bearing block is held in place by the pin 83. The spring 82 extends rearwardly and is pressedv down at suitable intervals by means of fingers 84 carried in the housing 85 in which'they are pressed downwardly by 1 suitable coiled springs. The

.downward pressure of the springs in the bars 23 '92 and 93.

Cross bars 100, 101 and 102 are provided to support the bars 22 and 22*, and the cross bar 103 is provided to support the air pump 66.- From the cross bar 103 extends spring 82 causes a modera bracket 104, see Fig. 1, from which. is Supported'the two ivots 105 and 106 on which are supported or swinging movement the arms 107 and 108. These arms are connected so as to swing together and the arm 108 carries the pin 109 which engages with 112 and 113 are provided in the chute for ing screws 115 fastened to the front of the.

the cam 110 carried on the shaft 13 by which an oscillating movement is given to the arms 107 and 108. At the rear end these bars carry a pusher plate 111 by which the pack.- ages are pushed out of the machine as they drop into the delivery chute. Flat springs holding the packages in an upright position. In using lab is of different lengths it is desirable to adjust the hopper 30 at the front end so that the top of the labels will always come into contact with the sucker. For this purpose the cross bar 11 1 is .provided in connection with the bearing block 47. In this bearing block, work the adjust- V andflllG, which support the cross bar 117 hopper. On this bar 117 are the locking screws 118 and 119 by which the bar 117 may be locked in place when it has been adjusted. A driving pulley 120 is loosely mounted on the main shaft 13 and a clutch 121 is provided on the shaft for coupling the pulley to the shaft. y
